6. Record the main anchor references, and any commentary/notes relevant for the

assessment of the condition and trends of each the species.

Species

Grading statements for different species assessed,

given what is best understood about their status and

trends expressed in terms of populations and groups of

species including threatened, endangered or protected

species.

Very Good (7-8)

Only a few, if any, species populations have declined as

a result of human activities or declining environmental

conditions

Good (5-6)

Populations of a number of significant species but no

species groups have declined significantly as a result of

human activities or declining environmental conditions

Poor (3-4)

Populations of many species or some species groups

have declined significantly as a result of human

activities or declining environmental conditions

Very Poor (1-2)

Populations of a large number of species or species

groups have declined significantly as a result of human

activities or declining environmental conditions

4.3 Ecological processes

To score ecological processes, experts will follow these steps:

1. Estimate a consensus score for the condition of ecological processes in the Best 10%

and Worst 10% of the habitat (eg. relative to 1900). Score both the area and

condition of ecological processes; for example if it is estimated that human activities

have caused the ecological processes to no longer occur in 10% or more of the

places where it did occur relative to the benchmark date, then the Worst 10% of that

ecological process will have a score of 1.

2. Estimate a consensus score for the condition of the ecological process in Most areas

(eg. relative to 1900).

3. Assign a confidence grade for each of the condition estimates (High, Medium, Low).

4. Estimate the trends for each of Best 10%, Worst 10%, Most (Improving, Declining,

Stable) over the last 5 years.

5. Assign a Confidence grade for each of the trend estimates (High, Medium, Low).

6. Record the main anchor references, and any commentary/notes relevant for the

assessment of the condition and trends of each the ecological processes.

Ecological Processes

Grading statements for the main ecological processes,

and affects from human activities

Very Good (7-8)

There are no significant changes in ecological

processes or ecosystem services as a result of human

activities

Good (5-6)

There are some significant changes in ecological

processes as a result of human activities in some areas,

but these are not to the extent that they are significantly

affecting ecosystem functions

Poor (3-4)

There are substantial changes in ecological processes

as a result of human activities, and these are

significantly affecting ecosystem functions in some

areas

Very Poor (1-2)

There are substantial changes in ecological processes
